Protein

ATP-dependent RNA helicase ded1

Gene

ded1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

ATP-binding RNA helicase involved in translation initiation. Remodels RNA in response to ADP and ATP concentrations by facilitating disruption, but also formation of RNA duplexes (By similarity). Inactivation of ded1 blocks mitotic cell cycle progression at G1 and G2/M. Induces sexual development and ascus formation.By similarity3 Publications

Miscellaneous

A different form of ded1 has been identified via SDS-PAGE studies. It is uncertain how this form arises in vivo.

Catalytic activityi

ATP + H2O = ADP + phosphate.
